McCain supporter calls Obama a ‘traitor’ at campaign rally.

At Sen. John McCain’s (R-AZ) rally in Wisconsin today, one woman screamed “traitor!” when McCain criticized Sen. Barack Obama’s (D-IL) tax record. Huffington Post notes that after the woman’s interruption, “both McCain and his wife Cindy appeared to look in her direction. The Arizona Senator continued with his stump speech without referencing her.” Watch it:

At another recent rally, a man yelled “Off with his head,” when McCain spoke about Obama’s tax plan. As even Fox News has noted, McCain’s rallies are becoming increasingly hostile. “In recent days, when Barack Obama’s name has been mentioned, it has gone from boos and hissing to actual chants and calls of traitor, criminal, and even terrorist,” reported Carl Cameron.
